Abstract
A new and green solvent-free syntheses of dimethylhexane-1, 6-dicarbamate from methyl-phenylcarbonate and 1, 6-diaminohexane were studied. The quantitative analysis method by high performance liquid chromatography for the reaction was developed and the process conditions were optimized. Suitable analytical conditions were found as follows: column Agilent ZORBAX SB-C18, mobile phase V(acetonitrile) : V(water)=55 : 45, column temperature 25°C, detection wavelength 200 nm and flow rate 0.8 mL/min. Under the optimum reaction conditions: reaction temperature 60°C, time 1 h and n(methylphenylcarbonate) : n(1, 6-diaminohexane)=2.5 : 1, the yield of dimethylhex-ane-1, 6-dicarbamate could reach 99.6%.
